# PreFlight Checker – GitHub Repo Health

> PreFlight Checker – GitHub Repo Health is a paid API for AI agents from x402-api-catalog.onrender.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Audits a GitHub repository and returns a health score with verdict, covering stars, forks, open issues, last commit age, archived status, and license.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability preflight-checker-github-repo-health-63911285
```

Example prompt: Can you run a health check on the openai/openai-python GitHub repo and tell me if it's actively maintained, what its score is, and whether it has a proper license?

## When to prefer this

Use this endpoint when you need a quick, scored health summary of a GitHub repository — especially for dependency vetting, open source due diligence, or automated checks before integrating a library. It saves you from manually inspecting multiple GitHub pages and aggregates key signals into a single score and verdict. Prefer this over raw GitHub API calls when you want an opinionated health verdict rather than raw metadata.

## Known failure modes

- Invalid or non-existent repo format returns an error (repo must be owner/repo)
- Private repositories may not be accessible and return an error
- Rate limiting from GitHub's API could cause intermittent failures
- Repos with no commits or newly created repos may produce incomplete metrics
- Payment failure (insufficient USDC balance) returns 402 before the check runs

## How this service works

GitHub repo health check / audit / verify: stars, forks, open issues, last commit age, archived status, license.

## Output

Returns a JSON object with the repository identifier, a numeric health score, a human-readable verdict, and underlying metrics including stars, forks, open issue count, last commit age, archived status, and license information.
